Figure 5. MEGNO stability maps superimposed on an upper mass-limit function of a hypothetical perturber. A MEGNO of around 2 indicates quasi-periodic (regular) orbits. A MEGNO of 5 or larger indicates ...
We present new ways to identify single and multiple moons around extrasolar planets using planetary transit timing variations (TTVs) and transit duration variations (TDVs). For planets with one moon, ...
Transiting exoplanets in multi-planet systems have non-Keplerian orbits which can cause the times and durations of transits to vary. The theory and observations of transit timing variations (TTV) and ...
The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...
Scientists from UNSW Sydney have located a potential new exoplanet – a planet that orbits a star outside of our solar system – using a technique known as ‘transit timing variation’. In research ...
TOI-1136, a dwarf star located more than 270 light years from Earth, is host to six confirmed exoplanets and a seventh as yet unconfirmed candidate. The system has provided a rich source of ...
Even though the ingredients for life have been confirmed to be practically everywhere we look, the only world where we've definitively confirmed its existence is Earth. Exoplanet science has exploded ...
